Paul-Adrien Bourdaloue
Paul Adrien Bourdaloue (4 January 1798, Bourges - 21 June 1868, Bourges) was a French civil engineer and topographer, who proposed the first orthometric levelling of France. Life Head of the Corps des Ponts et Chaussées, then engineer-resident of the Chemins de fer du Gard, from 1847 he carried out the levelling of the area of the future Suez Canal in Egypt at the request of the engineer Linant de Bellefonds. During this process he and others noted that the difference in levels between the Mediterranean and Red Sea was negligible, contrary to the conclusions of Bonaparte's engineers on the Egyptian Expedition such as Jacques-Marie Le Père. In 1857, he was commissioned to move onto the general levelling of mainland France. From 1857 to 1863, he laid out a network of 15,000 iron seals across France, providing the country's first level-lines. He was maire-adjoint of the town of Bourges. In 1865, he entrusted to the architect Albert Tissandier Albert Tissandier (1839 &nda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bourges
Bourges () is a commune in central France on the river Yèvre. It is the capital of the department of Cher, and also was the capital city of the former province of Berry. History The name of the commune derives either from the Bituriges, the name of the original inhabitants, or from the Germanic word ''Burg'' (French: ''bourg''; Spanish: ''burgo''; English, others: ''burgh'', ''berg'', or ''borough''), for "hill" or "village". The Celts called it ''Avaricon''; Latin-speakers: ''Avaricum''. In the fourth century BC, as in the time of Caesar, the area around it was the center of a Gallic (Celtic) confederacy. In 52 BC, the sixth year of the Gallic Wars, while the Gauls implemented a scorched-earth policy to try to deny Caesar's forces supplies, the inhabitants of Avaricum begged not to have their town burned. It was temporarily spared due to its good defences provided by the surrounding marshes, by a river that nearly encircled it, and by a strong southern wall. Julius Caes ...

French Campaign In Egypt And Syria
The French campaign in Egypt and Syria (1798–1801) was Napoleon Bonaparte's campaign in the Ottoman territories of Egypt and Syria, proclaimed to defend French trade interests, to establish scientific enterprise in the region. It was the primary purpose of the Mediterranean campaign of 1798, a series of naval engagements that included the capture of Malta and the Greek island Crete, later arriving in the Port of Alexandria. The campaign ended in defeat for Napoleon, leading to the withdrawal of French troops from the region. On the scientific front, the expedition eventually led to the discovery of the Rosetta Stone, creating the field of Egyptology. Despite early victories and an initially successful expedition into Syria, Napoleon and his Armée d'Orient were eventually defeated and forced to withdraw, especially after suffering the defeat of the supporting French fleet at the Battle of the Nile.

Water Tower
A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a water distribution system, distribution system for potable water, and to provide emergency storage for fire protection. Water towers often operate in conjunction with underground or surface service reservoirs, which store treated water close to where it will be used. Other types of water towers may only store raw (non-potable) water for fire protection or industrial purposes, and may not necessarily be connected to a public water supply. Water towers are able to supply water even during power outages, because they rely on hydrostatic pressure produced by elevation of water (due to gravity) to push the water into domestic and industrial water distribution systems; however, they cannot supply the water for a long time without power, because a pump is typically required to refill the tower. A water tower also serves as a reservoir to help with water needs during peak us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Tissandier
Albert Tissandier (1839 – 5 September 1906) was a French architect, aviator, illustrator, editing, editor and archaeologist. He was the brother of adventurer Gaston Tissandier with whom he collaborated in writing the magazine ''La Nature'', a French language scientific journal aimed at the popular science, popularization of science. He and his brother demonstrated the first electric powered flight. Early years and ''La Nature'' Born in Paris in 1839, Albert Tissandier was a loyal and assiduous companion of his brother, Gaston Tissandier. As an architect, he was involved in a large number of projects. Though his brother was nominally the sole founder of ''La Nature'', a scientific journal aimed at the popularization of science, Albert contributed extensively to the magazine, mostly as an illustrator and editor. He was heavily involved in it from the very first issue in 1873 until his retirement in 1905, less than a year before his death. Aviation career His devotion to aer ...

Mayor
In many countries, a mayor is the highest-ranking official in a municipal government such as that of a city or a town. Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role. A mayor's duties and responsibilities may be to appoint and oversee municipal managers and employees, provide basic governmental services to constituents, and execute the laws and ordinances passed by a municipal governing body (or mandated by a state, territorial or national governing body). Options for selection of a mayor include direct election by the public, or selection by an elected governing council or board. The term ''mayor'' shares a linguistic ...

Survey Marker
Survey markers, also called survey marks, survey monuments, or geodetic marks, are objects placed to mark key survey points on the Earth's surface. They are used in geodetic and land surveying. A ''benchmark'' is a type of survey marker that indicates elevation (vertical position). Horizontal position markers used for triangulation are also known as ''triangulation stations''. '' Benchmarking'' is the hobby of "hunting" for these marks. Types All sorts of different objects, ranging from the familiar brass disks to liquor bottles, clay pots, and rock cairns, have been used over the years as survey markers. Some truly monumental markers have been used to designate tripoints, or the meeting points of three or more countries. In the 19th century, these marks were often drill holes in rock ledges, crosses or triangles chiselled in rock, or copper or brass bolts sunk into bedrock. Today in the United States, the most common geodetic survey marks are cast metal disks with stamped l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jacques-Marie Le Père
Jacques-Marie Le Père (Paris, 25 April 1763 – Granville, 15 June 1841) was a French civil engineer. Life He accompanied the French Campaign in Egypt and Syria, was director of 'Ponts et Chaussées' (bridges and roads) in Egypt. After accompanying the expedition to the remains of the Canal of the Pharaohs, built by Necho II between the River Nile and the Gulf of Suez and improved by Ptolemy II, he was commissioned by Bonaparte to edit an account of the Canal. He was made a member of the Institut d'Égypte on 22 August 1798, in the mathematics section. With his brother Gratien and other engineers working alongside them, he carried out three building programmes (from 19 January to 5 February 1799, in September 1799, and finally in November to December 1799) to measure the levels of the isthmus, in difficult conditions due to Bedouin attacks and the lack of water. In the rain, he concluded that there was a 9 m difference between the levels of the Mediterranean and Red Sea, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
